From the Chinese folk medicine "Zhu jie xian fu" (roots of Anemone raddeana REGEL, Ranunculaceae), two new oleanane-type glycosides, named raddeanosides R8 (1) and R9 (2), were isolated. The structures of 1 and 2 were determined as 3-O-alpha-L-rhamnopyranosyl-(1----2)-O-beta-D-glucopyranosyl- (1----2)-alpha-L-arabinopyranosyl oleanolic acid 28-O-alpha-L-rhamnopyranosyl-(1----4)-O-beta-D-glucopyranosyl-(1----6)-b eta-D- glucopyranoside and 3-O-alpha-L-rhamnopyranosyl-(1----2)-O-beta-D-glucopyranosyl-(1----2)-al pha-L- arabinopyranosyl 27-hydroxyoleanolic acid 28-O-alpha-L-rhamnopyranosyl-(1----4)-O-beta-D-glucopyranosyl-(1----6)-b eta-D- glucopyranoside, respectively.
从中国民间药物“猪屎仙妇”（毛茛科植物林荫银莲花的根）中，分离得到了两种新的齐墩果烷型糖苷，命名为林荫银莲花苷R8（1）和R9（2）。化合物1和2的结构分别确定为3-O-α-L-鼠李吡喃糖基-(1→2)-O-β-D-吡喃葡萄糖基-(1→2)-α-L-阿拉伯吡喃糖基齐墩果酸28-O-α-L-鼠李吡喃糖基-(1→4)-O-β-D-吡喃葡萄糖基-(1→6)-β-D-吡喃葡萄糖苷和3-O-α-L-鼠李吡喃糖基-(1→2)-O-β-D-吡喃葡萄糖基-(1→2)-α-L-阿拉伯吡喃糖基2β-羟基齐墩果酸28-O-α-L-鼠李吡喃糖基-(1→4)-O-β-D-吡喃葡萄糖基-(1→6)-β-D-吡喃葡萄糖苷。
